3 Claims.

This invention relates to devices for priming internal combustionengines.

The general object of the invention is to provide a device forintroducing a starting fuel into an engine intake for starting theengine.

Another object of the invention is to provide a device of the characterindicated which will not interfere with the normal functioning of theengine.

With the foregoing object, as well as others, which will appear, in mindthe invention consists in the combinations and arrangements of parts,and details of construction, which will now first be fully describedwith reference to the accompanying drawing and then be more particularlypointed out in the appended claims.

In the drawing:

Fig. 1 is a schematic elevation View of a device embodying the inventionin a preferred form, showing also the mounting thereof on an engine;

Fig. 2 is an enlarged view of a part of Fig. l, and is partly in centralvertical section;

Fig. 3 is an exploded view, partly in section of a filler funnel and capincorporated in the device of Fig. 2; and

Fig. 4 is a plan view of the iiller funnel of Fig. 3.

In Fig. 1, the numeral I indicates an engine block to which is attachedan intake manifold 2, supplied with fuel air mixture by carburetor 3.Air filter 4 serves to remove dust from the air intake to thecarburetor. This filter is generally of known type, comprising anannular outer shell I0, the lower part of which may contain a body ofoil II, and an annular inner container I2 filled with suitable filtermaterial I3. The shell I and container I2 surround and are supported bya pipe I4 which connects to the carburetor intake. Cover I5 of thecontainer I2 is fastened down by a wing nut I6 on a central rod I1supported by a cross bar I8 in the pipe I4. Openings and 2I provide forflow into and out of the lter space within container I2, and a baille 22prevents direct flow from the space between shell I0 and container I2into the pipe I4. The course of flow of the air is downwardly in theshell I0, up through openings 20, through the filter material I3,through openings 2I and thence down the pipe I4.

The priming device comprises a cup 25, threaded at 26 to take screw cap21 and crimped to form a ange 28 which holds a wire gauze or similarstrainer 29 in position. Below the strainer the cup is provided with atapering spout 30 for directing starting uid into the pipe I4,

thus furnishing the iiuid direct to the carburetor and intake manifold,without passing through the filter material I3. The cup 25 fits snuglywithin an opening in the cover I5, resting on iiange 28, and the jointmay be sealed in any desired way, as by soldering, to prevent airleakage. For easy starting in cold weather, extremely volatile fluid maybe desirable. The fluid, when poured in the cup 25, quickly passesthrough the screen or filter 29 and spout 3D and drops into pipe I4,which is directly above the carburetor intake.

What is claimed is:

1. A priming device for engines having an air filter, comprising a cupand a duct leading therefrom to the engine intake at a point beyond theair filter material, and a vcover for the said cup, whereby startingfuel may be supplied to the engine without passing through the ltermaterial and the normal operation of the engine is not interfered withwhen said cup is closed by said cover.

2. A priming device for engines having an air lter with cover,comprising a cup mounted on the air filter cover, and a duct leadingtherefrom to the engine intake at a point beyond the air lter material,and a cover for the said cup, whereby starting fuel may be supplied tothe engine without passing through the filter material and the normaloperation of the engine is not interfered with when said cup is closedby said cover.

3. A priming device for engines having an air filter with cover,comprising a cup mounted on the air filter cover and spaced from thecenter thereof, and a duct leading therefrom downwardly and to thelcenter of 'the air filter at a point beyond the air filter material,and a cover for the said cup, whereby starting fuel may be supplied tothe engine without passing through the filter material and the normaloperation is not interfered with when said cup is closed by said cover.
